DETACHABLE FOUNTAIN OR RESERVOIR FOR PENS.

SPECIFICATION forming part of Letters Patent No. 619,528, dated February14, 1899.

Application filed April 23, 1898- To all whom it may concern.-

Be it known that I, JAMES K. YOUNG, a citizen of the United States,residing at Meriden, in the county of New Haven and-State ofConnecticut, have invented certain new and useful Improvements inDetachable Fountains or Reservoirs for Pens; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention has relation to detachable fountains or reservoirs forpens; and the object of the invention is to provide a simple, durable,and inexpensive device of this character that may be attached to nearlyall forms of pen-points now in use and by means of which the annoyanceof the writer in the frequent dipping of the pen will be reduced to aminimum and by means of which the flexibility of the nibs of thepen-points may be varied to adapt the pen to light or heavy strokes.

With this object in view the invention consists in certain features ofconstruction and combination of parts hereinafter fully set forth.

In the drawings, Figure 1 is a perspective view illustrating theapplication of my invention to a pen-point of the ordinary construction.of the fountain or reservoir removed. Fig. 3 is a bottom plan view. Fig.4 is an edge view. Fig. 5 is a longitudinalsectional view through thepen-point and fountain, showing in full lines the relation of parts whenit is desired to use the pen for making heavy strokes and in dottedlines the position of parts when the pen is used for light strokes; andFig. 6 is a view of a modified form of my invention.

In the accompanying drawings, 1 denotes the penholder, 2 the pen-point,and 3 my im- The fountain is struck up from'a single piece of material,such as aluminium, celluloid, non-corrosive metal, as brass, Germansilver, or nickel, and

is provided with an arched body portion 4, terminating at one end in atransversely-curved horizontally-projecting point 5, that engages thenibs of the pen, and with a rearwardlyprojecting transversely-curvedportion 6, that Fig. 2 is a detail perspective view.

fitsover the curved shank of the pen. Struck out from the arched portionis a tongue in the shape of a T-head, the shank 7 of which is curvedrearwardly and the head 8 of which extends transversely across thedevice.

In placing the fountain in position on the pen-point it is first crossedat right angles to the length of the point, so that the transverse headmay enter the slit or eye at the upper ends of the nibs. The fountainis-then turned quarter-way around until its point rests on the upperfaces of the nibs and its transverselycurved portion engages the shankof the pen, the curvature of the shank of the T-head being such as toexert a slight spring or tension, and thereby hold the fountain inposition.

When it is desired to make heavy lines with the pen-point, the fountainmay be slipped longitudinally to the rear end of the pen, thus allowingfree action of the nibsthat is, permitting them to separate to make aheavy stroke. For fine lines the device is moved toward the free ends ofthe nibs, and by exerting a pressure on the nibs near their pointsserves to stiffen said nibs, and thereby enable the writer to make finelines.

In Fig. 6 I have shown a modified form of my invention, in which theT-head is made by slitting the arch in the opposite direction.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A reservoir for the purpose described, comprising the arched bodyportion having projecting downward therefrom a T-head adapted to engagethe slit of a pen, and outward therefrom a point, and rearward therefroma transversely-curved portion, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
